The length of the square pool is 8. 49cm
<h3>How to determine the area</h3>
Note that the formula for finding the area of a square is given as;
Area = length^2
We have
Area = 72 m²
Substitute into the formula
I^2 = 72
Find the square root of both sides
I= √72
I = 8. 49cm
The length of the square pool given as I is 8. 49cm
Thus, the length of the square pool is 8. 49cm

Answer:
$2
Step-by-step explanation:
To use a percent you must change it to a decimal.
8% is .08
To find 8% of 25, we use multiplication.
.08 × 25
= 2
In case you cannot use a calculator or you want to be very quick about this, or just do a simple check... you can actually reverse the number (money, amount, etc) and the percent.
25% of 8 is not bad for doing mental math. 25% is a quarter, or 1/4 of 8 which again is 2.
Formula for the area of a quarter circle: A = (pi x r^2) / 4
A = (3.14 x 64) / 4
A = 200.96 / 4
A = 50.24 square yards

Answer:
k = 6.5
Step-by-step explanation:
y = 2x + c is given. Thus, we know immediately that the slope of this line is m = 2. If (k, 10) is a point on this line, then the following must be true:
10 = 2(k) + c, and
-3 + 2(0) + c
or
10 = 2k + c
c = -3
Thus, 10 = 2k + -3 becomes 13 = 2k, so that k = 6.5
